A Gram-stain-negative, aerobic, non-motile and coccoid, ovoid or rod-shaped bacterium, designated W-WS1(T), was isolated from wood falls collected around Wando, an island located in the South Sea, Republic of Korea. Strain W-WS1(T) grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 0-3.0% (w/v) NaCl. Phylogenetic analysis, based on 16S rRNA gene sequences, showed that strain W-WS1(T) belonged to the genus Pedobacter , clustering coherently with the type strains of Pedobacter daechungensis , Pedobacter lentus , Pedobacter terricola , Pedobacter arcticus and Pedobacter glucosidilyticus , showing 94.3-96.3% sequence similarity. Strain W-WS1(T) exhibited 16S rRNA gene sequence similarity values of 91.2-94.0% to the type strains of other species of the genus Pedobacter. Strain W-WS1(T) contained MK-7 as the predominant menaquinone and iso-C(15 : 0), iso-C(17 : 0) 3-OH and summed feature 3 (C(16 : 1)ω7c and/or C(16 : 1)ω6c) as the major fatty acids. The major polar lipids detected in strain W-WS1(T) were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain W-WS1(T) was 37.7 mol%. The differential phenotypic properties, together with its phylogenetic distinctiveness, revealed that strain W-WS1(T) is separated from recognized species of the genus Pedobacter . On the basis of the data presented, strain W-WS1(T) is considered to represent a novel species of the genus Pedobacter , for which the name Pedobacter silvilitoris sp. nov. is proposed. The type strain is W-WS1(T) ( = KCTC 42174(T) = CECT 8669(T)).
从韩国南海一个名为莞岛周围收集的木落物中分离出一株革兰氏阴性、需氧、不运动、球状、卵形或杆状细菌,命名为W-WS1(T)。菌株W-WS1(T)在30 °C、pH 7.0 - 8.0以及0 - 3.0%(w/v)NaCl条件下生长最佳。基于16S rRNA基因序列的系统发育分析表明,菌株W-WS1(T)属于Pedobacter属,与大忠Pedobacter、迟缓Pedobacter、土生Pedobacter、北极Pedobacter和葡萄糖分解Pedobacter的模式菌株紧密聚类,序列相似性为94.3 - 96.3%。菌株W-WS1(T)与Pedobacter属其他种的模式菌株的16S rRNA基因序列相似性值为91.2 - 94.0%。菌株W-WS1(T)以MK-7作为主要甲基萘醌,以异-C(15 : 0)、异-C(17 : 0) 3-OH和总和特征3(C(16 : 1)ω7c和/或C(16 : 1)ω6c)作为主要脂肪酸。在菌株W-WS1(T)中检测到的主要极性脂为磷脂酰乙醇胺和一种未鉴定的脂质。菌株W-WS1(T)的DNA G+C含量为37.7 mol%。其不同的表型特征及其系统发育独特性表明,菌株W-WS1(T)与Pedobacter属已确认的种不同。根据所提供的数据,菌株W-WS1(T)被认为代表Pedobacter属的一个新种,为此提议将其命名为林地Pedobacter(Pedobacter silvilitoris)新种。模式菌株为W-WS1(T)(=KCTC 42174(T)=CECT 8669(T))。
